PANTOGR-APHEC APPARATUS.

Applicationjled January 21, 1228. Serial No. 248,444;

This invention relates to theatrical appa-ratus and more particularly tothe construction and control of an animated dummy to permit duplicationof certainoperations performed by a concealed operator. i

An important object of the invention is to provide an apparatus wherebya dummy may duplicate cartoons or other drawings delineated by theconcealed operator.

A still further object of the invention `is to produce mechanism foraccomplishing these objects whicli'is extremely simple in both itsconstruction and operation, which is readily manipulated andwhich willbe durable and These and other objects I attain by the constructionshown inthe accompanying drawings, wherein for the purpose ofillustration is shown a preferredembooliment of my invention and whereinv Figurel is a side elevation partially in section showing theatricalapparatus constructed in accordance with niy invention; Y

Figure 2 is a section on'the line 2- 2 of Figure 1, the-dummy beingillustrated in dotted lines;

Figure 3 is a. section on the line 3-*3 of Figure 1;' Y y Figure l isV aplan `view of the operators arm mechanism showing the coaction with thepattern; l,

Figure 5 is a'detail section-al view through one end of the controlmechanism;

Referring nowv more particularly to the drawings, the numerals 10 and 11indicate operators and dummys easels, of which the operators easel hasclips 11 for interchangeably supporting panels 12 upon which patterns 13are producedk for the guidance of the operator. Below the panel, theeasel 10 has secured to one leg thereofa guide element 14,' the puiposeof which will presently appear.'

The easel 11 has mounted thereon a transparent panel 15 and has securedthereto at its upperend and at its rear face a rotatable roller 16supporting al paper roll 17, the web from which is passed overthe upper'end ofthe easel and downwardly over the front face thereof and thencebeneath the lower end of the panel 15 to afwindingroller 18. Thiswinding roller has at oneend thereof a worm gear 19. Secured to theeasel 11 ata point corresponding to the position of the guide lll of theeasel 1() is a container 2O7 for the reception of ink or paint;

The easels 10 and 11 are preferably ai'- ranged adjacent opposite endsof a platform 21 and arising from this platform are Astandards-22suitably bracedV to oneanother and to the platform. These supports arearranged adjacent the easels 10 and 11 and the support adjacent theeasel 10 has secured thereto a bracket 23, through which is rotatablydirected a shaft2t having at its rear end a. crank .25, and at itsforward end, 'whichis rotatably directed vthrough a bracket 26 carriedby the easel 11, a worin 27 for engagement with the` worm gear 19`of thewinding roll 18, so that this winding roll may be rotatedto draw palperfrom the paper roll 17. The roll 16 supporting the paper roll has at itsend a ratchet disk28 and the adjacent bracket 29 by means of which thisroll issupported from the easel llmo-unts a pawl 30 releasable by astring 31 extended adjacentvtheeasel 10, by means of which the rollmaybe locked against rotation. Ars the worm gearing employed for theoperation of the winding roll likewise serves to lock this roll, itywillbe obvious that the paper l may be drawn tightly across the face oftheeaselv and secured in this position. j

The upper ends of the supports 22 have' eX` tending upwardly therefromspaced guides 32 between which ata point spaced below the lupper endsthereof are rollers 38. Mounted upon these rollerslbetween the guides 32is an assemblage'comprising inner and outer tubular .shafts 341 and 35,of which the inner shaft 34; is of greater length than theshaft and hasits ends` 'extended beyondthe ends there-- of. The outer shaft 35 hassecured thereto spaced stop collars coacting with one of lthe pairs of.guides to limit longitudinal movement of the assemblage overy therollers. Y lt will beobvious that this assemblage may be either rotatedjvithin thelimits defined by these stop colars.

between the inner and outer shafts 34 and 35, the shaft Salispreferably'of less external diameter than theA internal diameter of theshaft 35 and the shaft 35 has mounted iii-itsV or longitudinallyVshifted In order to reduce frictional 'contact i ends bushings 37 in'which the shaftfl may be rotated. The outerends ofthe shaft 34 l havesecured thereto an V.upper arm element 38, to the lower end of whichisvpivotally connected,l as at 39, a forearm structure 40j both theupper arm and forearm elements prefer# ably consisting of flat plates.Theouter ends of the shaft 35 havesecured'thereto .short arms 41connected by links42 to the forearm structure at a point spaced from thepivot 39 thereof, so that rotation of the shaft 35, While the shaft 34is stationary, Will result in an oscillation of the forearm elements 40about their pivots 39. It Will, of course, be obvious that. movement ofthe forearm or upper arm elements 38 or 40 at either end of thestructure will be duplicated at the-opposite end of the structur. Thearm structure at the forward end of the easel 11 is incorporated in andconcealed by the clothing of a dummy 4,3., The end of the forearmstructure is formed as the hand of the dummy and constructed to supporta brush or stylus 44. The forearm element adjacent the easel 1()V isprovided Wi th a stylus 45 constructed to co-operate with the pattern13.` The pattern 13 employed is preferably provided by a groove or ribformed upon the panel 12 in the desired shape. The easel 10 and theassociated arm mechanism may be concealedl tainer. 20. yThe stylus isthen moved to the pattern and passed thereovei'. The operator through asuitably foi'med opening in the booth Wall and through the transparentpanel 15 may observe the progress of the reproduction and in event offailure of the fluid of the stylus 44, may again dip this `stylus intothe container 9.() to replenish the same. The pattern completed, the webmay be` shifted to present aclean surface by manipulation of the crank.

It will be obvious that in moving the stylus 44 from the container 2()to the sheet, the entire mechanism should be shifted outwardly,

so that this stylus Will not contact the sheet until it arrives at theproper point.

Since theV construction hereinbefore set forth is capable of a certainrange of change and modification Without materially departone of saidtubes, forearm elements pivoted to the ends of said arms, respectively,rela-f tively short arms secured to the respective ends of the other ofsaid tubes, links connecting the ends of each short arm toits adjacentforearm element whereby similar movements ving the ends of each shortarm to its adjacent forearm 'element whereby similar movements aretransmitted to said forearm elements, styli carriedby said elements formovement over the respective panels, acabinet enclosd ing the panelbearing the pattern `and the associated arm mechanisms of the-tubes anda dummy in an arm of which the `arm mechanism at the opposite ends ofthe tubes is included.
